In this case, thin does equal delete.

Further, TimeMachine does need to delete the actual files to free up more space. My guess is that it's quick because many of the items to delete will be hard linked directories, which should dramatically bring down the number of files to delete. rsync can only hard link files, so there's going to be much more to remove. > Reason I ask is I do backups with rsync's --link-dest option, which I like, > but there's the problem of deleting the oldest timestamps, as it takes a > while... > > Any way to bend the laws of physics? My email backup (from offlineimap) contains several tens of thousands of files and really slowed down TimeMachine (every backup had to check every file to determine which were new in the directory). So I switched to rsnapshot, which handled the many files much faster, but still wasn't exactly speedy. Now I just rsync directly to the backup location (running on FreeNAS) and rely on ZFS snapshots to quickly make and prune old backups. Apple really should have just executed on their ZFS project. -- arno s hautala /-| [email protected] pgp b2c9d448 _______________________________________________ MacOSX-talk mailing list [email protected] http://www.omnigroup.com/mailman/listinfo/macosx-talk
